The fragrant cream-white flowers, which can appear from late winter until mid spring are in axillary or terminal long tight racemes. Plant in a well-drained soil in full to part coastal sun and part day sun in hotter inland locations. Irrigate occasionally. Hardy to moderate frosts and responds well to pruning but seems sensitive to heavy soils, where it is prone to root rot. This species is endemic to sandy soils in Western Australia. This form was selected for its attractive new red foliage and flowers for the UCSC Koala Blooms program and was released for sale in 2008 under the cultivar name 'Picasso'. The specific epithet 'synapheae' is in reference to this plant's perceived similarity to the genus Synaphea, another Proteaceous genera from Western Australia. A beautiful and unusual grevillea but one that needs excellent drainage, otherwise is prone to root rots. This limitation made us decide to discontinue production of this plant in 2014.  The information that is presented on this page is based on research we have conducted about this plant in our library and from reliable online sources. We also consider observations we have made of it in the nursery's garden and in other gardens we have visited, as well how it performs in our nursery crops out in the field. We incorporate comments that we receive from others as well and welcome getting feedback from anyone who may have additional information, particularly if they know of cultural information that would aid others in growing  Grevillea synapheae 'Picasso'.     [MORE INFO]
